U.S. curler Matt Hamilton looks like he’s ready to level up in this year’s Winter Olympics.

Matt and Becca Hamilton made their Olympic debut in the Games’ first match of mixed doubles curling. The brother and sister team started to go viral after one user on Twitter pointed out Hamilton’s resemblance to Mario from the “Super Mario” video game.

“Just watching the olympics during my night class and we have Mario on our curling team!!” Twitter user @douglasturtle wrote.

The official account of the U.S. Olympic team saw his tweet and replied with a picture of Hamilton next to a photo of him with Mario’s face photoshopped on the curler’s head.

“Spot the difference @MJamilton,” the U.S. Olympic team tweeted.

“These two pictures are the same,” the Twitter user replied.

Other Twitter users also chimed in and joined in on the joke.

I see the difference…the one on the right is missing the back shoe. Or is it the difference in the size of the nose? Nah, it’s the missing shoe.

While many had fun on Twitter, the Hamiltons started the doubles curling tournament with a 9-3 win over Russian couple Anastasia Bryzgalova and Aleksandr Krushelnitckii.

Unfortunately for the team, they’d lose their second match, 6-4, to the Canadian team of Kaitlyn Lawes and John Morris.

Mixed doubles is happening for the first time at the Pyeongchang Games. The tournament is a round-robin played by teams of one man and one woman.

The Hamilton siblings teamed up three years ago after they learned mixed doubles would become a part of the Olympics, ESPN reports. Mixed doubles comes to an end on Tuesday and both Hamiltons will compete separately in the men and women’s tournaments.

Both are hoping to go home with medals that are as gold as the power stars from “Super Mario.”
